60 Starfish Experiment

Decent Essays
Discussion:
MY HYPOTHESIS THAT A DECREASE IN STARFISH POPULATION WILL RESULT IN A DRAMATIC INCREASE IN MUSSEL POPULATION was supported by my data. I started with an amount of 60 Starfish in my tidal pool. The results of this scenario was that the average amount of Mussel population was 99 at 60 Starfish. As we went down the line in the number of Starfish present in the start of the experiment the number of Mussel population increased. With the amount of 20 Starfish, the Mussel population averaged at 202.67- over double as much as with 60 Starfish. I then went to 0 Starfish in the tidal pool and was shocked with my results. With 0 Starfish, the Mussel population averaged 426.33, dramatically higher than with 20 Starfish to the point where Mussels

This species’ particular invasion is becoming an increasingly dangerous issue due to the lake’s close proximity to other bodies of water, many of which flow into the DuPage River, a huge water source and aquatic habitat for the surrounding area. Hundreds of thousands of nature enthusiasts visit Mallard Lake on a yearly basis, and the threat of continuous spread is expected unless the public and professional community can work together to slow the process. In order to do this, scientists from all over the world are studying and experimenting with zebra mussel populations in order to better understand their ability…

    The role oysters play in the Bay ecosystem is their ability to filter water so efficiently. A century ago, “oysters by the billions once thrived in the Chesapeake. No more. Over fishing and parasitic diseases called MSX and dermo have all but ended the harvest” the numbers now are so low, some speculate if it could even be possible to resurrect their populations even marginally. With polluting waters, oysters must work overtime filtering through water, trying to find beneficial nutrients.…

    Scientific Validity of “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” Coral reefs are having a problem with pH levels and they are dying some places around the world right now, because of it. This is not only affecting the coral reefs, but the animals that live in them and survive with them. There is a Scientific Study called “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” which discusses the behavior and neurological impairments of coral reef fish due to more CO2 and acidic levels of pH. More CO2 causes lower levels of pH and makes it more acidic and very dangerous for fish. Overall this is a poor scientific article, because it has only one good source…

    This is a paper about a the Chesapeake Bay and how its food chain works, what the roles of the organisms are, the possible effects of a decrease in population of the algae, plants, and animals, also the possible causes for this and why as well as the preventions being done against this as well as the fixing of them. Also what else could be done or should be done about the issue. That is the main topic and subject this paper is gonna talk about. There are many organisms within the Chesapeake Bay food chain and they allow a well surviving, well healthy environment, and without these little tiny or maybe big organisms this life and environment for them as an ecosystem will fail and could cause a problem of a becoming of overabundant of algae and cause many problems starting with killing off of oxygen and reducing of it which would cause a reduction of sunlight with the reduction of…

    During this lab observations of the external and internal structures of seastars were examined through dissection. Most notably, seastars are creatures that are deuterostomes. First of all, deuterostomes are organisms within Echinodermata and Chordate phylum that developed anus first. The egg for echinoderms have a little quantity of yolk that allows the egg to divide in its first and second cleavage stage into four equal blastomeres; this is also known as holoblastic cleavage. Although, if the egg is macrolecithal then it will undergo meroblastic cleavage, in which the embryo can divide in a restricted space that is yolk-free in the cytoplasm (small dic area).…

    A short YouTube video by Hank Green provides an easily understood run down of evolutionary adaptations. Green gives examples of evolutionary traits in starfish, octopi and humans. For starfish, Green uses the evolution of the starfishes’ eyes. Some species of starfish have evolved eyes that allow them to find food more easily than those species that have evolved without them. Green also relates how some octopi have evolved with copper and the protein hemocyanin in their blood which combine to make oxygen transport more efficient.…
